摘要
目的研究递增负荷运动至力竭后血清肌酸激酶、乳酸脱氢酶的动态变化,探讨补充复合磷脂对细胞膜通透性的影响,为在运动中补充复合磷脂提供实验依据。方法10名受试者服用复合磷脂3周,分别在服用前,1,2,3周后安静时,力竭运动后和次日晨检测血清CK,LDH活性,并与10名对照组比较。结果补充复合磷脂1周进行力竭后血清CK从服用前的(5.38±0.30)μmol/(s·L)降至(3.98±0.27)μmol/(s·L),次日晨从(3.33±0.30)μmol/(s·L)降至(2.43±0.25)μmol/(s·L),其下降具有显著性差异(P<0.05);而血清LDH从服用前的(6.78±0.47)μmol/(s·L)降至(5.77±0.42)μmol/(s·L),次日晨从(4.65±0.37)μmol/(s·L)降至(3.12±0.30)μmol/(s·L),其下降同样具有显著性差异(P<0.05)。结论补充复合磷脂后血清CK,LDH降低,说明复合磷脂具有保护细胞膜结构的完整性的作用。
Aim To study the diversification of serum CK and lactate dehydrogenase (LDH) after fatigue and investigate the effect of the supplement of compound pho sphatide on permeability of cell membrane for the supplement of compound phospha tide during the motor exercise.Methods Ten healthy volunteers aged 19-21 from G uangzhou P.E. College, were asked to take compound phosphatide for 3 weeks, and other ten volunteers were used as controls. The concentration of serum CK and ac tivities of LDH were detected before treatment, at the quiet state of 1,2 and 3 weeks after treatment, immediately after exhaustive exercise and in the next mor ning after exhaustive exercise respectively, and then was compared with control group in results.Results The concentration of serum CK[μmol/(s·L)] in the expe rimental group taking compound phosphatide for 1 week reduced from (5.38±0.30) to (3.98±0.27) immediately after exhaustive exercise, and from (3.33±0.30) to( 2.43±0.25) in the next morning after exhaustive exercise, with a significant di fference(P< 0.05).The concentration of serum LDH[μmol/(s·L)] in the experiment al group reduced from(6.78±0.47) to (5.77±0.42) immediately after exhaustive e xercise, and from (4.65±0.30) to (3.12±0.30) in the next morning after exhaust ive exercise, also with a significant difference(P< 0.05).Conclusion After the s upplement of compound phosphatide, the concentrations of serum CK and LDH reduce significantly.It is indicated that compound phosphatide is effective in prevent ion of the integrity of cell membrane structure.
